Restructured nltk.draw.wordnet_browser:

 + This no longer keeps a list of previously served pages
 + This no longer uses the contents of a page as a source of
   information to resolve the next query.
 + The contents of a page can now be modified in one part of this
   program without affecting the behaviour of another.
 + URLs now contain all the information necessary to resolve a query.
 + A number of methods have been marked as deprecated.
 + The start page is now generated dynamically rather than statically
   so that as changes are made it does not need to be manually updated
   to conform to those changes.
